We have recently purchased 6 SmaFan Voyager 52” Smart Ceiling Fans, one from Amazon and the other five directly from SmaFan. Upon installation, remote pairing and testing, only one of the six units works as advertised. Two barely work at all, if you want the fan or lights to function on those units you will need to hold the button on the remote for up to 10 seconds. One unit shuts off on its own, and to work again requires you to cycle power to the circuit. The remaining two units are flakey, you need to hold a button for at least 2-3 seconds to get anything to work. After contacting Smafan customer support, they admitted that there is a known issue with the control boxes and that their fans do not work well. Without sincerity, sympathy or a “we are sorry for your inconvenience”, we are instructed that they will take the units back for a refund, or they will send new control boxes. This is all good and well, except their customer now gets to remove six fans and either return or repair and re-hang with the hope that they now work as advertised. This is terrible customer service, I do not understand how a business that operates like this can remain in business, and maybe they are simply struggling and won’t.
